中文摘要	The solidification structures of cast Fe-B-C alloy containing more than 2.0%B and lower than 0.2%C and the structures and properties of alloy after heat treatment were researched by means of optical microscopy (OM), scanning electron microscopy (SEM), X-ray diffraction (XRD), hardness measurements, impact tester and pin abrasion tester. The results show that the solidification structures of cast Fe-B-C alloy consist of boride (Fe2B), pearlite and ferrite, and boride distributes along grain boundary in network form. After normalizing at 950 degrees C, the part broken network of boride in cast Fe-B-C alloy appeared, the matrix all transformed into lath martensite. The hardness of cast Fe-B-C alloy increased obviously and neared to HRC 60, its impact toughness and dynamic fracture toughness exceeded 10 J/cm(2) and 30 MPa.m(1/2), respectively. In the condition of pin-on-disk wear, cast Fe-B-C alloy showed excellent abrasion resistance. Its abrasion resistance is more excellent than that of Ni-hard white cast iron, GCr15 and Cr12MoV, nears to that of high chromium white cast iron. Cast Fe-B-C alloy has simple melting process and good casting property, does not contain costly nickel and molybdenum elements and so has low production cost.
